SPECIFICATION forming part of Letters Patent No. 714,601, dated November 25, 1902. Application filed September 26, 1902. $eria1 No. 124,949. (No model.)

5 invented certain new and useful lmprovements in ApplyingCorkStrips to Cigarette- Paper; and I do hereby declare the following.

to be a full, clear, and exactdescription of the invention, such as will aenable others skilled in the art to which it appertains to make and use the same. I

The present invention relates to. a device for applying cork strips to a cigarette-paper strip at suitable intervals, in which the pieces is of cork are partially severed from the strip and guided on the way to the rolls for applying the same. to the paper strip, so that they shall be applied to the said stripin proper position and exactly at that-part of the same which has previously been provided with an adhesive, thenext following piece of corki be ing-reta-ined in proper position during this operation...) r i 1 In order-to render the present specification easily intelligible, reference is had to the ac companyingdrawings, in which like letters of reference indicate similar parts throughout.

Figure l is-a side elevation of suchparts of;

the apparatus as are necessary for the proper.

3o understanding of one embodiment of the in-l vention, and'Fig. 2 is a similar view of a modi-3 fied form of the same.

In bothembodiments the strip 0 of having been previouslyprovided with an adhesive at suitable intervals by means of the roll a.

cigarette-paperis guided between the pressure- 1 3 5 rolls b m infront of the table t', the said strip Thislatter mechanism is known and forms no part of the present invention. The

0 rolls a and bare run at the same speed in opposite directions bytmeans of suitable connections through the pulleysk and 7c,'mounted on theshaftJcd. The cork'strip is taken from the roll 01 ina bande of paper wound with the cork strip on-the said roll'and is fed over the table 1 toand' below the paper strip a and with it to the rolls 6 m. The band 6 is drawn downward between the roll at and a lower roll after effecting the transfer of the cork strip to the rolls 1) m. i

The detachment of each piece of cork which has previously been partially severed by the cutter f is completed by the. cooperation of the roll at with the raised face a of the roll I) rotating in the opposite-directiom In Fig. 1 the severing is effectedby these two rolls drawing in the next piece of cork, While the piece next-but one, which has been partially severedby the cutter f, isretained by .a presser-loot h onthe. table and thus the total severence prevented forthe time being. .The face at also presses the corkslip or piece against that part of the cigarette-paper strip provided with the adhesive.- The cutter fand the presser-foot h are depressed atthe proper moment by means of a cam g. While the foot 71 holds the piece of cork down on the table t', the cutter f makes an incision about two-thirds of the thickness of ,the cork strip in order to partially sever the nextsection or length. This. incision enables each length to be properly detached subsequently, leaving smooth edges. The operation of the presser-foot prevents the cork strip from curling up and insures the cutting of exactly the proper length each time. The partially-severed length of cork is not released .by the foot 71. until the face a" of theroll b again'comes around and, cooperating with roll m, draws the cork piece between the said rolls. The lower roll 'm of itself exercises no ,upward pressure on the cork piece, since this roll is cylindrical and has no raised face. The arrangement of the raised face a; on the roll b above the strip 6 and behind the paper strip 0 necessitates the arrangement of the raised face of the roll Ct alternately of the face case that the two faces operate alternately 011 the strip 0 and not simultaneously. prevent the face as from tearing the paper strip, which it would do if it were to grip the same while the face of the roll a, was in operation.

In the device describedwith regard to Fig.

cork which is required for immediate use by This is necessary in order to the rolls 1) m, the incision taking place at the moment the front end of the piece of cork is gripped by the rolls. Thus the necessity of the presser-foot is obviated, and a roll h may be substituted for the same, said roll being mounted on the table at the immediate rear of the cutter f and serving to hold the end of the corkstrip flat down on the table. This has the additional advantage that the end of the cork strip cannot be carried upwardly by the ascending cutter, which might possibly happen in the case of the device illustrated in Fig. 1.

In the device shown in Fig. 2 in order to obviate the necessity of having a transporting-band of paper wound upon the cork roll (1 an endless band 6 for the support of the cork is provided running over roll m and guide-rolls e and c the'latter of which is adjustable to enable the said band to be tightened up at will. In order to properly press the cork onto the paperstrip, a second supplemental pair of rolls m b may be employed, the latter of which has a raised face 00 to press the cork onto the paper strip.

I claim as my invention 1. A device for applying strips of cork to a continuous strip of cigarette-paper at suitable intervals, consisting of a table onto which the end of a strip of cork coming from a roll of cork is fed, means for holding the end of the said strip down on the table, means for making an incision in the said strip at a point equal to the length to be detached, and a pair of rolls, one having a raised face, between which said rolls the cigarette-paper strip, previously provided with an adhesive at certain points, is fed, the said raised face being timed to cooperate with the second roll and grip, cut

1 ing an incision inthesaid strip at a point equal rolls, one having a raised face, between which said rolls the cigarette-paper strip, previously provided with an adhesive at certain points,

is fed, the said raised face being timed to co- I operate with the second roll and grip, cut and press the'detached piece of cork onto the adhesive of the paper strip substantially as described.

3. A device for applying strips of cork to a continuous strip of cigarette-paper at suitable intervals, consisting of a table onto which the end of a strip of cork coming from a roll of v to the length to be detached, and a pair of 5o cork is fed, a roll to depress the end of the said strip down on the table, a reciprocatory cutter for making an incision in the said strip at a point equal to the length to be detached,

continuous strip of cigarette-paper at suitable intervals, consisting of a table, a roll of cork mounted in proximity thereto, an endless band to feed the end of the same to the said table, means for holding the end of the said strip down on the table, means for making an incision in the said strip at a point equal to the length to be detached and a pair of rolls, one having a raised face, between which said rolls the cigarette-paper strip, previously provided with an adhesive at certain points, is fed, the said raised face being timed to cooperate With the second roll and grip, cut and press the detached piece of cork onto the adhesive of the paper strip substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
